Durability and lightness coexist in harmony thanks to the new outsole / midsole package with external Rubber Guard ™ shell construction and internal foam material for accentuated cushoning and lightness derived from less use of rubber layers. The shape is Ergonomic: enveloping and precise with integrated TPU shells in the toe and heel to reinforce the upper. The 3D Flex System Evo ™ directional joint with shaped malleolus and anti-abrasion protection, allows better control of the support and perfect mobility of the ankle. The protective gaiter on the toe lacing protects against chafing. The midsole is semi-cramponable, the sole adopts a Vibram® tread with Impact Brake System lugs for greater adaptability to hard rock surfaces. Mountaineering in perfect harmony.
